OF AKRON, ILLINOIS,

Letters .Patent No. 95,658, dated October 12, 1869.

nvrrnovnn EXCAVATOR.-

The Schedule referred tom these Letten Patent and making part of the same.

To all Icham it may concern:

Be it known that we, JAMES GoWDEN, of LaPrai- `rie Centre, Marshall county, Illinois, and DANIEL BROWN, of Akroniln the county of Peoria, in the State of Illinois, have invented an Improved Excavator; and

we do hereby declare that the following is a full, and

A A represent the wheels, which are made to4 run on axle R R, fig. 1, arrangedpto turn in frame N N, to which poles P P P are attached for the purpose of op# erating the excavator. These wheels have a series of elevators made through them, as seen at B B, Ste., figs. 1.and 2, diagonally with the axle R, and near the peripheries of said wheels,l which are made to roll upon the ground.

Said elevators are designed to carry the earth, loosened by a plow, G,'up\vard and into a dumpingbox, S, fig. 1, which is designed to transport it to any desired place.

The plow G is attached to a lever, I, by means oi' a shank, H, which can be raised or 4lowered in a guide, L, by means of a rod, M, and lever,-T, iig. l, in the usual manner; the front end of said lever beingr attached to a support, J, by means of `a joint, K, in order to give plow G a vertical motion.

The wheels A A can be made of wood or iron, asv

most convenient, but if woodis used, strong, wide tire should be shrunk on their peripheries, and the elevators B B should be lined in order to prevent wear.

A scraper, C, g. 1,.is arranged to t'against the inside of each wheel A, for the purpose of cleaning the earth l from said wheels, and causing it to fall into dumping-box'S. i. l

A guide, D, is attached to one or more of the elevators B for the purpose of giving the proper direction to the earth after it has been elevated. We consider the said guide important inthe matter of con-v veying sand, loam, clay, Ste., into the dumping-box S, as the character of dili'erent soils may require a different pitch at the discharge-end of the elevator in orderv that their direction may be controlled.

The method of securing the guide consists in put# ting a pin, f, throughslotse e, fig. 3, and through a loop -or other fastening attached to the inner surface' of the elevators B, by which means the guide can '-be set at any desired pitch.

l A rim, V, is attached to the periphery of wheels A, A andmade to cover such a portion. of the elevator B asis necessary to keep the earth -in -place when being carried up.

It will be seen from this description that the 4earth is made to enter the elevators B directly opposite the A plow G, and is then carried up by the 'motion of the wheels. v

--In the drawings, a double or atwo-wheeled excavator is shown, but it may be desirable at times to have o'nly one wheel; this can be made to operate equally well, but will require a change in the frame-work, to meet the case. I

`Having thus fully described our invention, I

What we claim, and desire to secure -by Letters Patent, is

1. Broadly, the guides D, constructed asy described, I

to give direction to the earth when passing through elevators B, as herein specied.

2. The combination of elevators B, rim V, and scraper C, with guide D, substantially as set forth.

`3. Making theguide D adjustable, substantially as herein set forth.
